While Bernie Sanders continues to serve as the public thorn in Hillary Clinton’s side with victories like the one in Indiana Tuesday, he’s stuck to his pledge not to bring up Clinton’s “damn emails.” In that arena, Judicial Watch continues to be the engine that could, chipping away for years at Clinton’s scandal-proof Teflon coating.

It might be hard to believe, but Sanders is doing conservatives a huge favor by motivating progressive Democrats to join in their demand that Clinton’s scandals be investigated. And if the timeline in Judicial Watch’s approved discovery plan plays out as scheduled, Hillary Clinton might be called to testify just weeks before the Democratic National Convention.

Clinton claims setting up her own insecure home-brew email server and domain was a matter of convenience, but U.S. District Court Judge Emmet G. Sullivan found that a suit filed by Judicial Watch raises significant questions about the real purpose of the server; that is, was the whole point of setting it up to route documents out of State Department possession in order to circumvent FOIA requests?

Although the judge has left open the possibility of Clinton testifying based on information learned during discovery, top Clinton aides will be called upon to testify first. They include Clinton’s chief of staff Cheryl Mills, deputy chief of staff Huma Abedin, Bryan Pagliano, who set up and maintained Clinton’s server, and three others.

Judicial Watch reports that the discovery will take place over the next eight weeks, meaning it would conclude in July, followed by a determination whether to call Clinton to testify — meaning that things could really heat up for Clinton this summer.
